| Abstract | The container carriers represent a challenge in the design process, where an important role play the estimation of design loads and their response. The wave-induced vibrations are often referred to as whipping as a transient phenomenon due to wave impacts and springing as a resonance phenomenon due to oscillating loads. These hydro-elastic vibratory phenomena’s are the most important consequences of the continuous increase in the ship length and low stiffness of the hull girder. While this is a concern in the marine industry, this phenomenon is not clearly considered in the design. Therefore, there are uncertainties associated with the wave-induced vibration intensity and the probability of occurrence of whipping to the sea state that needs to be clarified. This paper address the effect of the relationship of the characteristics of whipping vibration to the sea state, evaluating the results of a series of time-domain computational simulations. A numerical method that combines a three-dimensional panel method and FEA proposed by one of the co-authors is employed for evaluating the load effects. The calculations are performed for the respective short-term sea states. This study presents the probability of occurrence and vibration intensity of the whipping vibration experienced by a 6500 TEU container carrier in a North Atlantic Ocean route. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
